Cystic fibrosis (CF), the most common autosomal recessive disease in Caucasians, is due to mutations in the CFTR gene. F508del, the most frequent mutation in patients, impairs CFTR protein folding and biosynthesis. The F508del-CFTR protein is retained in the endoplasmic reticulum (ER) and its traffic to the plasma membrane is altered. Nevertheless, if it reaches the cell surface, it exhibits a ...
F508del is the most common mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene that is responsible for the genetic disease Cystic Fibrosis (CF). It results in a major failure of CFTR to traffic to the apical membrane of epithelial cells, where it should function as a chloride (Cl-) channel. Most studies on localization, processing and cellular trafficking of wild-typ...
RATIONALE Tezacaftor (formerly VX-661) is an investigational small molecule that improves processing and trafficking of the cystic fibrosis transmembrane conductance regulator (CFTR) in vitro, and improves CFTR function alone and in combination with ivacaftor. OBJECTIVES To evaluate the safety and efficacy of tezacaftor monotherapy and of tezacaftor/ivacaftor combination therapy in subjects w...
Mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene cause CF. The most common mutation, F508 deletion, causes CFTR misfolding and endoplasmic reticulum retention, preventing it from trafficking to the cell surface. One approach to CF treatment is to identify compounds that correct the trafficking defect. We screened a marine extract collection and, after extract, de...
Biosynthesis and folding of multidomain transmembrane proteins is a complex process. Structural fidelity is monitored by endoplasmic reticulum (ER) quality control involving the molecular chaperone calnexin. Retained misfolded proteins undergo ER-associated degradation (ERAD) through the ubiquitin-proteasome pathway. Our data show that the major degradation pathway of the cystic fibrosis transm...
Tezacaftor/Ivacaftor in Subjects with Cystic Fibrosis and F508del/F508del-CFTR or F508del/G551D-CFTR
The new CFTR modulator combination, elexacaftor/tezacaftor/ivacaftor (Trikafta) was approved by the FDA in October 2019 for treatment of Cystic Fibrosis patients 6 years age or older who have at least one F508del mutation allele and a minimal-function another other allele. However, there is group patients, addition to those with rare mutations, which despite presence allele, it not possible ide...
INTRODUCTION In this study we investigated the effects of the Cystic Fibrosis Transmembrane conductance Regulator (CFTR) gene variants on the composition of faecal microbiota, in patients affected by Cystic Fibrosis (CF). CFTR mutations (F508del is the most common) lead to a decreased secretion of chloride/water, and to mucus sticky secretions, in pancreas, respiratory and gastrointestinal trac...
Cystic fibrosis (CF) is the most common fatal autosomal recessive disease in Caucasians. since characterization of F508del, the predominant mutation in different countries, more than 1500 mutations have been discovered in the CFTR gene, including a large number of polymorphisms. After molecular screening of 222 CF patients from serbia, we detected 21 different CFTR mutations, F508del being the ...
